Milk May Delay Knee Osteoarthritis in Women

JAMA. 2014;312(4):327. doi:10.1001/jama.2014.8698

Frequently drinking fat-free or low-fat milk may slow the progression of osteoarthritis of the knee in women but not men, according to a prospective study of 1260 women and 888 men (Lu B et al. Arthritis Care Res. doi:10.1002/acr.22297 [published online May 27, 2014]).

At the start of the study, researchers collected dietary data and measured joint space width (JSW) by x-ray to evaluate osteoarthritis progression, with additional measurements done at 12, 24, 36, and 48 months. As a woman’s intake of milk increased (from none, ≤3, 4-6, and ≥7 glasses/wk), the mean decreases of JSW were 0.38 mm, 0.29 mm, 0.29 mm, and 0.26 mm, respectively.
